摘要
Provided is a silicon carbide spacer which is capable of suppressing the occurrence of breakages due to spark plasma sintering to enable stable spark plasma sintering. This spacer for spark plasma sintering is a silicon carbide spacer 12 that includes silicon carbide and has a frustoconical shape. The silicon carbide spacer 12 is placed, in a spark plasma sintering device 1, between a punch 112 of a mold 11 for spark plasma sintering that has a cylinder 111 and the punch 112, and a pressurization ram 14 that applies pressure to the punch 112, with the small flat surface 21 of the frustoconical shape disposed on the punch 112 side. Additionally, the diameter (ds) of the small flat surface 21 is preferably configured such that the ratio thereof to the punch 112 diameter (a) satisfies the relationship 1≤ds/a≤1.5.
